ENGINEERING

Growing the technology that the Livings are built from

Not every piece of work has to be forced into one of the six Livings. Technology we gain through client projects and research is kept as Engineering, and what grows there is fed back into the Livings.

The cycle between Living and Engineering

  1. STEP Learn the technology on client work
  2. STEP Keep it in the company as Engineering
  3. STEP Put it to use in a Living
  4. STEP Improve it there
  5. STEP Bring the know-how back to clients

Learn it on client work, use it in a Living, and bring it back to clients.

Scattered tools, brought into one flow.

Every Living service sits on the same foundation: LINE, Web, Google Sheets / Excel, freee, AI, Automation. From the first contact with a customer through booking and purchase, customer records, sales, accounting, analysis, and on to the next action — it all becomes one continuous flow.
